Method Detail

shardInitialized

void shardInitialized(ShardRouting unassignedShard,
                      ShardRouting initializedShard)

Called when unassigned shard is initialized. Does not include initializing relocation target shards.

shardStarted

void shardStarted(ShardRouting initializingShard,
                  ShardRouting startedShard)

Called when an initializing shard is started.

relocationStarted

void relocationStarted(ShardRouting startedShard,
                       ShardRouting targetRelocatingShard)

Called when relocation of a started shard is initiated.

unassignedInfoUpdated

void unassignedInfoUpdated(ShardRouting unassignedShard,
                           UnassignedInfo newUnassignedInfo)

Called when an unassigned shard's unassigned information was updated

shardFailed

void shardFailed(ShardRouting failedShard,
                 UnassignedInfo unassignedInfo)

Called when a shard is failed or cancelled.

relocationCompleted

void relocationCompleted(ShardRouting removedRelocationSource)

Called on relocation source when relocation completes after relocation target is started.

relocationSourceRemoved

void relocationSourceRemoved(ShardRouting removedReplicaRelocationSource)

Called on replica relocation target when replica relocation source fails. Promotes the replica relocation target to ordinary initializing shard.

startedPrimaryReinitialized

void startedPrimaryReinitialized(ShardRouting startedPrimaryShard,
                                 ShardRouting initializedShard)

Called on started primary shard after it has been promoted from replica to primary and is reinitialized due to shadow replicas.

replicaPromoted

void replicaPromoted(ShardRouting replicaShard)

Called when started replica is promoted to primary.

initializedReplicaReinitialized

void initializedReplicaReinitialized(ShardRouting oldReplica,
                                     ShardRouting reinitializedReplica)

Called when an initializing replica is reinitialized. This happens when a primary relocation completes, which reinitializes all currently initializing replicas as their recovery source node changes
